For tax cheat Geither to talk about honest investing is absurd - if he wants better law enforcement he should send himself to prison.

As for how to prevent wild speculation - how about NO BAILOUTS (there was not just one last year - Greenspan was doing a de facto bailout every time he increased the credit money supply in response to threats of the bubble bursting, year after year). Accept of course that tax cheat Geither and the Fed (and the Treasury) were in favour of the great bailout orgy of last year and this (for the expansion of the money supply is still going on - more than ever in fact).
